Abstract (en)
[origin: US4721108A] A generator for pulse trains of shockwaves for the purpose of contactlessly comminuting concretions in living bodies, comprising a shockwave source, for instance a spark gap, a focusing reflector, for instance a hollow ellipsoid filled with a propagation medium, and a layer of a material having an impedance different from that of the medium of propagation mounted in such a manner that it is crossed by the shockwave field.
